Twenty-four states have enacted long-term (3+ years), specific energy savings targets, which can take the form of a statewide Energy Efficiency Resource Standard (EERS), long-term energy savings targets set by utility commissions tailored to each utility, or incorporating energy efficiency as an eligible resource in renewable portfolio standards (RPS). This fact sheet provides brief summaries of each state electric and natural gas EERS, including reference legislation and orders. The fact sheet also discusses the findings of two recent reports: Energy Efficiency Resource Standards: A Progress Report on State Experience and Energy Efficiency Resource Standards: State and Utility Strategies for Higher Energy Savings.
